Premium Letterhead & Digital E-Card

I need a polished A4 corporate letterhead and a matching digital e-card that capture the professionalism of Maina Nexus, my industrial real-estate advisory focused on warehouse leasing and industrial land deals. You have full freedom to propose a color palette that feels modern, trustworthy, and suited to the industrial sector—I haven’t locked anything in yet.

The letterhead must visibly carry:
• Company logo
• Contact information
• Company tagline

Once the design is approved, please supply:
• Editable source files (AI or PSD)
• Print-ready PDF
• Transparent PNG
• A Microsoft Word-compatible version of the letterhead

The e-card should echo the same visual language, ready for email distribution and easy resizing for social media headers if needed. Clean hierarchy, generous white space, and impeccable typography are important to me; think premium stationery that instantly signals credibility to warehouse owners, investors, and corporate tenants.

If you have previous examples of minimalist or industrial-themed stationery created in Adobe Illustrator or Photoshop, that will help me gauge fit quickly. Looking forward to seeing your concept.
